OEM A-body rear sway bar

The diameter of the bar is about 3/4 inch. The link arrangement is on the bar, both sides. Brackets are a no. The brackets I have are on my car with a bar. The frame rail brackets are just a U-shaped bracket similar to 1976 Charger and attach in a similar fashion. The brackets at the springs are similar to (and interchangeable with) the Charger brackets. (I presume you are aware that there are minor differences with the Chargers such as (for example) isolated and non-isolated spring arrangements.) Some editions of the '76 parts catalog that I have seen show an illustration of the A-body rear bar. I do not have that illustration.
